METHOD OF MAKING BAG-TOPS.

Application filed January 3, 1921.

T all "whom it may concern:

Be it known that I, SAHATIEL Gr. MAN- DALIAN, a citizen of the United States, residing at North Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Methods of Making Bag-Tops, of which the following is a specification.

My invention relates to the bag tops of chatelaine bags, purses and the like.

In prior structures of this character the upper and end faces of the two jaws constituting the top have been ornamented but it has been impossible heretofore to apply stamped ornamentation upon the side faces of the jaws.

The essential objects of my invention are to render such ornamentation possible and to effect this end by a simple and inexpensive method of jaw construction.

To the above ends essentially my inventions consists in such steps and in such succession of steps as fall within the scope of the appended claim.

In the accompanying drawings which form a part of this specification- Figure 1 is a perspective view of a complete bag top,

Fig. 2, a similar view of the original blank from which a jaw is formed,

Fig. 3, a side elevation partially in central section of suitable rolls employed upon the original blank,

Fig. 4, a perspective view of the blank after the first operation,

Figs. 5 and 6, perspective views of the obverse and reverse blank after the second roll operation,

Fig. 7, a side elevation partially in central section of rolls convenient to perform the second rolling operation,

Fig. 8, a perspective view of the blank after the bending operation,

Fig. 9, a side elevation of rolls employed in bending the blank,

Fig. 10, a perspective view of the blank after the cutting operation, and

Fig. 11, a fragmentary perspective view illustrating the cutting operation.

Like reference characters indicate like parts throughout the views.

In performing my process represents an oblong strip of metal of rectangular cross section originally in the form shown in Fig. 2. This strip is then compressed by rolls Specification of Letters Patent.

16 and 17. The periphery of the latter being provided with a cavity 18 deeper at one end than at the other. The passage of the blank through these so compresses the metal that one face of the strip 19 is smooth and the other face is irregular havinga thick longitudinal portion 20 at one edge and a thin longitudinal portion 21 opposite thereto.

The blank is next passed between two companion rolls 23 and 24. The former has upon its middle portion an annular shoulder 25. The roll 24 has a peripheral cavity 26 intermediate its length provided at its bottom with an annular ornamented face, the ornamentation being in relief. The blank is passed through these rolls with the face 19 thereof in contact with the shoulder and receives a central longitudinal groove 28, while the opposite face of the blank throughout practically its entire width receives an ornamentation.

The blank is next passed through a pair of rolls 30 and 31. One roll has a V shaped shoulder 32 centrally of its length while the roll 30 has a cooperating V shaped groove 88 spaced somewhat from the shoulder. The blank in passing intermediate the shoulder and groove, as shown in Fig. 9, has imparted thereto, as shown in Fig. 8, a right angular bend intermediate its width along the groove 28 which groove permits the material of the blank to assume the rectangular position. This longitudinal bend produces in the blank 15 the two longitudinal portions 35 and 36 having respectively ornamental faces 37 and 38 respectively upon their outer faces.

At equal distances from the end of the blank an an ular shaped cutter 4O cooperating with the plate 41 is employed. This cutter is angular in cross section and descends transversely of the blank 15 producing a transverse V shaped groove 43 in the portion 35 and a V shaped cutaway portion 44 in the portion 36 of the blank. The portions of the blank outside the groove 43 are now bent inwardly toward each other thus closing the grooves 43 and the cutaway portion 44 which thus completes the jaw.

Fast by solder or otherwise to two jaws are perforated lugs 46 and 47 connected by pivoted members 49.

It will be observed that each jaw constructed according to the method described is provided with an ornamentation upon both its top end portion and upon its side portions, an effect heretofore unattainable in bag tops of this character.

I claim:

A method otmaking ornamental bag tops of the character described consisting of impressing an ornament upon the major por tion of the width of one face of an oblong blank, forming a longitudinal groove in an,

posed angularly to each other, next cutting transverse groovesin one section each side its center and cutting away angular portions of the other section in alinement with the last mentioned grooves next bending the blank along the transverse grooves, and finally pivotally connecting two such bent blanks.

In testimony whereof I have afiiXed my signature.
